The wrong cleaner causes permanent damage. Acid etches the surface of natural stone—marble, limestone, travertine. Solvents permanently damage the surface of porcelain gres coatings. Replacement costs more than using the right product.
After finishing work, the most common need is to remove grout residue, cement residue, and mortar stains. Acidic grout cleaner can be used on ceramic, porcelain gres, and glass mosaic—natural stone requires an acid-free formula because acid reacts chemically with limestone. This is not a matter of degree.
With regular maintenance, ceramic and porcelain gres are less sensitive, but the open pores of the grout surface continuously collect dirt. Regular ceramic grout cleaning prevents mold growth and preserves the overall appearance. Cleaning natural stone—granite, travertine, marble—always requires an acid-free tile cleaner.
On stone surfaces, stain formation and moisture penetration can be prevented—but timing of impregnation is crucial. On new stone surfaces, granite and travertine impregnation must be done before grouting because grout material does not bond to treated pores. On old stone, care follows marble or stone cleaning.
On outdoor facades, treating biological contamination—algae, mold, lichen—is the first step. After pretreatment, a deeply penetrating water-repellent impregnation protects vertical surfaces against rainwater and air pollution without changing the surface appearance. These two steps together provide durable facade protection.
Grout residue, epoxy, and polyurethane foam can be removed when fresh—after curing, removal requires disproportionately more effort. Tool cleaners are designed for this critical time window. Immediate tool cleaning after concrete floor cleaning and grouting saves the next job.
